Description of Habitat/Range:

This species is common throughout eastern United States and parts of Canada. It is usually found at a variety of streams and rivers, including streams with intermittent rapids and emergent vegetation. Riparian trees providing shade seem to be one of preferences for its habitats. The ebony jewelwing tends to be found at smaller forested streams than the river jewelwing. This species is very common and widespread at flowing waters throughout Wisconsin.

Shading illustrates monthly percentages of the total flight season records for the species.
Each flight season record is a unique date/location/observer combination where one or more adult or an
exuvia was recorded (excludes nymphs). The actual number of flight season records for each month is shown
in parentheses.

Flight seasons begin earlier in the southern
part of the state, often by a week or more. Also, flight charts may not be accurate for rare species because of
few data available.
